>Description:


cc -print-search-dirs should print the installation location of cc, and where support files can be found.
The lcc sources (at least the included one for Q3A) use this flag.




>How-To-Repeat:


Expected behavior:
$ cc -print-search-dirs
install: /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/
(from a linux system)

Behavior on FreeBSD:
$ cc -print-search-dirs
install: /usr/libexec/(null)



>Fix:


This patch fixes the (null). DragonflyBSD uses a similar, but longer change to remove the use of machine_suffix completely.
